When adding, place digits in columns and sum accordingly; for subtraction, align numbers and borrow if necessary for correct calculation. Multiplication involves arranging numbers to multiply digit by digit, while division requires dividing numbers and carrying over remainders for accurate results.
Insights
- In addition, digits are added column by column, regardless of the order of numbers, ensuring that zeros are appropriately placed to maintain the correct place value in the final sum.
- Subtraction requires the larger number to be on top, potentially necessitating borrowing when subtracting to ensure accurate results, as demonstrated by the example of 546 - 47.6.
